I can get a much better price on JL w3 rated at 6 ohms that at 4 or 2.

My question is, since w3s are dual voice coil, by hooking the subs coils up in parallel, I would actually be able to operate at 3 ohms, and not be loosing power, correct?  Any reason I should avoid doing this?

should have been "not loose much power" would be operating 1 ohm higher than 4 ohm dual voice in parallel.

Are you using one sub...and with what type of amp (two channel, mono)?
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

JL 300/4..........3 ohm stable bridged.  Thinking about 1 sub for now.

OK...150 watts looks like the optimum power to give that sub (W3v2).  That amp will produce the same power whether the impedance load is 3 ohms or any number up to and including 8 ohms, so you'll do well to get your good deal on the sub.  Use two channels bridged for the sub and the other two channels for your mains.
